DetectionBaseModel.label() file handling improvement

[n0kovo]

This PR implements two updates to DetectionBaseModel.label():

1. ef83ab8 - Handling for multiple extensions and recursive search:

   • Added support for specifying multiple file extensions via extensions (list) argument.
     This is backwards compatible and defaults to a single extension.
   • Added recursive directory search option via recursive (bool) argument.

2. f8e6e47 - Truncated image loading and improved error handling:

   • Added capability to process truncated images (useful in scenarios where the dataset might contain partially corrupted or incomplete files).
   • Enhanced error resilience during image processing.

Please let me know if anything needs changing.
